PAVING-TOOL.

Specification of Letters Patent.

Patented Feb. 28, 1911.

Application filed October 4, 1910. Serial No. 585,177.

To all whom it may concern:

Be it known that I, AARON WV. Srmornn, a citizen of the United States,residing at Durham, in the county of Durham and State of North Carolina,have invented certain new and useful Improvements in Paving Tools, ofwhich the following is a specification.

This invention relates to apparatus for spreading the top stuff orwearing surface of cement or granolithic sidewalks, and it has for itsobject to provide a device of this kind which can be easily operated,and which is highly efficient in operation, and capable of certainadjustments to be hereinafter described.

In order that the invention may be better understood, reference is hadto the accompanying drawing, forming a part of this specification, inwhich drawing,

Figure 1 is a front elevation of the device, in operative position, thesidewalk being shown in section; Fig. 2 is a side elevation of thedevice; Fig. 3 is a plan view thereof; Fig. 4 is a cross section on theline a-a of Fig. 3, and, Fig. 5 is a perspective view of a differentscraper blade.

Referring specifically to the drawing, the device comprises a wheeledframe carrying a scraper blade, and provided with a handle. The wheeledframe comprises spaced side pieces 5 which are connected across by asectional bar, the two sections of which are indicated at 6. Thesections overlap and are bolted together, and their inner ends are bentto extend along the inner faces of the side pieces as indicated at 6 andare secured thereto by bolts or other suitable fastening means 7 and 7respectively.

To the outer faces of the side pieces 5 are secured handles comprisingrearwardly extending side bars 8 which are connected at their outer endsby a grip which is in two sections, indicated at 9 and 10, respectively.The section 9 is tubular, and the other section extends thereinto, toform a telescopic joint for a purpose to be presently described. Thesections are locked in adjusting position by means of a set screw 11which is threaded through the tubular section to engage that portion ofthe other section which extends thereinto.

On the outer faces of the side pieces 5 are mounted wheels 12 and 13. Tothe inner faces of the' side pieces 5 are secured guide memberscomprising shanks 14- carrying rowels15. The shanks let are secured bythe bolts 7, the latter also serve as the axles of the rear wheels 12.The axles are steadied by braces 16 extending therefrom to the sidepieces 5.

The bolts 7 pass through vertical slots 17 in the parts 6 in order thatthe sections 6.

may be raised or lowered with respect to the side pieces 5. The sections6 carry a scraper blade 18 which is bolted or otherwise secured theretoso as to extend transversely between the side pieces 5. The lower edgeof the blade is below the corresponding edge of the sections 6, and inFig. 1 said lower edge of the blade is shown as serrated. In Fig. at isshown a blade 19 having a straight lower edge. The blade 18 will be usedfor leveling the concrete, after which the blade 19 will be used forsmoothing the surface of the concrete. The blades will be made invarious lengths so that the tool may be used on side walks of differentwidths. The tool can be readily adjusted according to the length of theblade desired, by disconnecting the sections 6 and loosening the setscrew 11. The bolts which fasten the sections 6 together also serve tosecure the blade.

In operation, a blade is selected to suit the width of the sidewalk, andthe tool is then adjusted according to the length of said blade, and thelatter is fastened in place. The tool is supported above the bed ofconcrete by means of the wheels 12 and 13, said wheels traveling on theside rails 20 of the form which incloses the bed of concrete. By meansof the handle, the tool is now carried back and forth across theconcrete, the serrated scraper blade spreading and leveling thematerial, after which it is smoothed by substituting blade 19. The bladeis located in front of the rear wheels 12, so that it may be elevatedabove the surface of the material by swinging the handles downwardly,the blade then swinging upwardly, the rear wheels serving as thefulcrum. The tool is prevented from rolling off the rails 20 by therowels 15, the latter sliding along the inner faces of the rails whenthe tool is in operation.

I claim:

1. A paving tool comprising spaced side members, a sectional cross-barconnecting said members, the sections of the cross-bar being adjustedrelatively to each other in the direction of their length, means forholding i scraper blade carried by the cross-bar;

from the side members, a sectional handgrip connecting said rearwardlyextending copies of this patent may be obtained for of their length,means for hol'dil g the sec-- tions in" adjusted past-i5 1; and scrape:-blade carried by thej cibss-bar.

In testimony whereof-I nflix my signature in'presence of two Witnesses.
